There’s a whiff of urban legend here, but I like it anyway. From a reader:

Jonah,
There’s a great French restaurant in Philadelphia that has had a five-star rating for several decades. It requires a second mortgage to pay the tab and features a wine list that would greatly impress a poseur like the Sideways character, Miles. A few years ago, according to the testimony of a buddy, a rather unassuming guy booked reservations for twelve and sat down in the tres chic dining room to enjoy a convivial evening with family and friends. After the somelier went around the table, noting everyone’s selections, he came to our host, who unabashedly ordered a Yuengling, the old reliable of Pennsylvania beers. The wine snob visibly winced and sniffed ,”Sorry, monsieur, we do not carry such a thing.” With that, the guy stood up and announced to one and all: “We’re leaving.” As fate would have it, the gentleman was a direct descendent of the original Pottsville brewing dynasty. And he was more than ready to take his friends, and his cash, and walk out the door.
